When it comes to building a commodity shed, a wide range of designs exists. However, when you talk to producers who are happy with their commodity sheds, you start to see a pattern of what works, says Mike Gamroth, extension dairy specialist at Oregon State University. He lists the following criteria for commodity shed design:

1. Slope bays outward so rain and snow melt don't flow into the storage bays.
2. Pour the concrete floors after the walls have been poured. This prevents water from leaking into an adjacent bay when cleaning between loads.
3. Slope the concrete apron in front of the bays away from the bays.
4. Design the commodity shed to have two more bins than you think you need. This allows you to rotate feeds, clean bins between loads and pre-mix commodities if desired
5. Include a bin for dry rolling or processing grain.
6. Place supplemental storage for bagged minerals in an adjacent building. A shed roof with a dry floor is adequate for sacked feeds stacked on a pallet.
